Method Detail

stop

public void stop()

Description copied from class: AbstractTransactionManager

Stops the transaction manager, performing all implementation specific cleanup.

Specified by:

stop in class AbstractTransactionManager

init

public void init(XaDataSourceManager xaDsManagerToUse)

Description copied from class: AbstractTransactionManager

Begins the transaction manager, possibly triggering a recovery. The passed xaDsManager, given the startup sequence of the neo kernel, is assured to already have registered all xa resource adapters available for this run, so they can be used for registration for recovery purposes.

Specified by:

init in class AbstractTransactionManager

Parameters:

xaDsManagerToUse - The XaDataSourceManager that has registered the Xa resources.

attemptWaitForTxCompletionAndBlockFutureTransactions

public void attemptWaitForTxCompletionAndBlockFutureTransactions(long maxWaitTimeMillis)

Description copied from class: AbstractTransactionManager

Prevents new transactions from being created by throwing exception in beginTx and waits for all existing transactions to complete. When this method returns there are no transactions active and no new transactions can be started.
